The MPC5xxx SOCs have a MSCAN controller, which is different to the
Flexcan and handled by another driver. But the Flexcan's  on the
Freescale ARM SOCs are identical and supported by that driver as well
and "fsl,flexcan" would work *perfectly*. Actually Grant instructed use
to be more explicit and use "fsl,p1010-flexcan". Anyway,
"fsl,p1010-flexcan" should work on ARM SOCs if the source frequency is
provided via boot loader or the DTS file. Compatibility was one of our
main concerns.
